Question

I have a feeling this should be easy but I can’t seem to figure it out. I have a settings file, Settings1.settings, that has entries for 20 textboxes (n1 thru n10 and c1 thru c10).

Currently, I save the textbox text to the settings file on Form1_FormClosing like so:

Settings1.Default.n1 = n1.Text;
Settings1.Default.n2 = n2.Text;
...
Settings1.Default.n10 = n10.Text;

Settings1.Default.c1 = c1.Text;
Settings1.Default.c2 = c2.Text;
...
Settings1.Default.c10 = c10.Text;

How would I do something similar with a loop? My thought would be this, but obviously it doesn’t work:

int count = 1
while (count < 11)
{
    Control n = panel2.Controls.Find("n" + count.ToString(), true).Single();
    Settings1.Default.n = n.Text; //Settings1.Default.n is an invalid statement ...

    Control c = panel2.Controls.Find("c" + count.ToString(), true).Single();
    Settings1.Default.c = c.Text; //Settings1.Default.c is an invalid statement ...

    count++;
}

What’s the proper way to address “Settings1.Default.n + count” ?

Thank you!!

I would suggest changing the type of your settings “n” and “c” to “System.Collections.Specialized.StringCollection” and dealing with it like a regular list or array object, something like:

Settings1.Default.n.Clear()
Settings1.Default.c.Clear()
int count = 1
while (count < 11)
{
    Control n = panel2.Controls.Find("n" + count.ToString(), true).Single();
    Settings1.Default.n.Add(n.Text);

    Control c = panel2.Controls.Find("c" + count.ToString(), true).Single();
    Settings1.Default.c.Add(c.Text);

    count++;
}

Alternatively, I think you can also access the settings entries by string like this:

Settings1.Default["n" + count.ToString()] = n.Text;
